This wild mushroom polenta with porcini sauce is a sophisticated vegetarian dish that brings deep, earthy flavours to the dinner table. By combining the intense aroma of dried porcini with the crisp texture of oven-roasted chanterelles and shiitake mushrooms, you create a complex layering of textures. The silky, parmesan-enriched polenta provides the perfect comfort-food base, or 'bed', for the glossy, wine-reduced mushroom sauce to soak into.
Ideal for an elegant weekend supper or a vegetarian festive centrepiece, this recipe celebrates the best of forest flavours. While it feels indulgent, the use of high-quality vegetable stock and fresh herbs keeps the profile bright and balanced. Serve it immediately while the polenta is at its most creamy, perhaps with a side of garlicky wilted kale or tenderstem broccoli to complete the meal.

How to make Wild Mushroom Polenta with Porcini Sauce
Back to contentsIn a small bowl, combine porcini mushrooms and 240ml warm water. Let stand until mushrooms soften, about 30 minutes. Remove porcini mushrooms from the liquid, strain and reserve liquid. Finely chop the mushrooms and set aside.
While the porcini are soaking, set racks in the upper and lower thirds of the oven and preheat oven to 232°C. On two rimmed baking sheets, gently toss mushrooms with thyme and oil; season with salt and pepper. Roast mushrooms until edges are browned, about 10 minutes. Set aside until ready to use.
Heat oil in a large saucepan over medium-high heat. Sauté shallot until softened, about 5 minutes. Add garlic, and sauté for 2 minutes more. Add white wine and bay leaf and increase heat; boil until most liquid evaporates, about 7 minutes. Add reserved chopped porcini mushrooms, vegetable stock, and reserved mushroom liquid. Boil until liquid is reduced to 240ml , 15 to 20 minutes. Remove bay leaf.
In a small bowl, stir butter and flour together until it forms a paste. Whisk the butter mixture into the mushroom sauce. Simmer until sauce thickens, about 1 minute. Season with salt and pepper.
In a large saucepan, bring 1450ml water and the salt to a boil. Reduce the heat to medium-low and whisk in the polenta, whisking constantly to make sure there are no lumps. Cook, stirring occasionally with a wooden spoon, until thickened and cooked through, 15 to 20 minutes. Remove from heat; stir in the cheese,and butter. Season with salt and pepper. Serve polenta immediately topped with porcini sauce and roasted mushrooms.
